Pursue any question or area not directly related to the core topic. Every speaker hosts at least 4 sessions which means there are about 11 to 12 simultaneous sessions running all the time with an average of 5 or 6 participants.

Topic flexibility: If the audience raises a question which takes a speaker into an area not directly related to the core topic, then the group can agree to pursue that line and return to the core topic afterwards. This is only possible because the subjects indicated for the speakers are a proposal, a guideline rather than a strict rule.
